Maximum continuous burst8 fps6 fps
Lens detailDX-format angle of view approximately 1.5× FX focal length; supported G/E/D, AF and P lenses with restrictions. AI non-CPU lenses usable in manual mode with no metering; non-AI, IX and F3AF lenses unsupported.KAF4, KAF3, KAF2, KAF and KA lenses; KAF2 power-zoom operation is not supported. Autofocus behaviour depends on in-lens motor or the body screw drive
AutofocusViewfinder Advanced Multi-CAM 3500II phase detection with 51 points, 15 cross-type and centre point supporting f/8; −3 EV sensitivity at ISO 100 and 20°C. Dynamic, 3D tracking and group-area modes; live view uses contrast detection with face, wide, normal and subject-tracking modes.Through-viewfinder SAFOX X phase detection with eleven points including nine central cross-type points; EV −3 to 18 at ISO 100. Live-view hybrid sensor phase/contrast autofocus with face detection, tracking, multiple/select/spot areas and focus peaking
Shutter1/8000 to 30 seconds, Bulb and Time; mechanical focal-plane shutter and electronic front-curtain in mirror-up mode. Flash sync 1/250 second; up to 1/320 with reduced guide number, and compatible Auto FP.Mechanical focal-plane 1/6000–30 seconds and Bulb; timed Bulb 10 seconds–20 minutes; electronic shutter for Pixel Shift Resolution rather than a general high-speed electronic mode
Burst detailHigh-speed continuous approximately 8 fps with AF/AE tracking; low-speed 1–7 fps. Nikon states up to 50 lossless-compressed 14-bit RAW frames or 100 large Fine JPEGs under its published test conditions.Approximately 6 fps at ISO 100, up to 40 highest-quality large JPEGs, ten RAW or eight RAW/JPEG pairs; 3 fps low-speed mode up to 100 JPEGs, sixteen RAW or eleven pairs
Stabilisation detailNo sensor-shift stabilisation; optical VR depends on the attached lens. Electronic movie VR for Full HD/HD, unavailable for UHD.Sensor-shift SR; maker claims 4.5 shutter stops in launch notice. Pixel Shift Resolution has selectable subject-motion correction, which cannot correct every moving subject. Astrotracer needs optional O-GPS2; no built-in GPS inferred
FlashBuilt-in pop-up flash, guide number approximately 12 at ISO 100 in metres and 20°C; i-TTL, optical commander support and ISO 518 hot shoe. Optional AS-15 provides a sync terminal.Built-in retractable P-TTL flash, guide number approximately 12 at ISO 100 in metres; 28mm full-frame-equivalent coverage; 1/180-second sync and external dedicated-flash support
